Verification or qualification, is one main reason that costs for space systems are high. All data are to be documented and to stay accessible for potential, later failure analyses. In previous times that approach was executed down to piece-parts level (resistors, switches etc.) whereas nowadays it is tried to reduce cost by usage of "CAM ...
A protoflight approach carries a higher technical risk approach compared to a full qualification test program since it has no demonstrated life capability over the anticipated life cycle of the hardware, but is a technology development design process that utilizes higher risk tolerances, agile management practices, and quick responsiveness that ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
Another example is NASA's IV&V Program, which was established in 1993. [7] By the end of the 1970s IV&V was rapidly becoming popular. The constant increase in complexity, size and importance of the software led to an increasing demand on IV&V applied to software.
Process qualification is the qualification of manufacturing and production processes to confirm they are able to operate at a certain standard during sustained commercial manufacturing. Data covering critical process parameters must be recorded and analyzed to ensure critical quality attributes can be guaranteed throughout production. [ 1 ]
product certifications (many nations) Product certification or product qualification is the process of certifying that a certain product has passed performance tests and quality assurance tests, and meets qualification criteria stipulated in contracts, regulations, or specifications (sometimes called "certification schemes" in the product certification industry).
While there are differences between getting preapproved vs. prequalified, both processes usually involve credit checks: a soft check for prequalification and a hard check for preapproval.
Acceptance testing of an aircraft catapult Six of the primary mirrors of the James Webb Space Telescope being prepared for acceptance testing. In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
